This Desperately Needs Updating, I Can’t Even Use This On My Phone Anymore Because It’s Severely Outdated

### 1/5 — Crashes often

*2024-01-11, version 2.0*

After getting this app I removed it due to excessive crashes then for the next 3 months every time I tried to go onto the iPad it would give me multiple pop up error messages saying “need to update app fluidity keep/delete” except that the app was no longer on my device anymore. So the messages come up 10 times in a row because there was no app to update. So it was stuck in limbo for months. Finally had to fully reset the device re download the app update it and now deleting it hoping I never have to deal with it again.
